Overwatch – Periodically cleans up errors and eliminates junk that accumulates while you play. Also removes the “greater than 8” and “requires adult” restrictions. Mover – I use this mod to retains the dreams and opportunities of Sims when I switch active households. I also recommend the optional modules including Cheats, Integration, and Progression. Also allows you to select any Sim in the world. Master Controller – Adds options that allow you to control and change just about anything in your Sims 3 world. I also recommend downloading the optional modules for this mod especially Career, Extra, Money, Others, Population, Relationship, and Skill. Story Progression – Replaces EA’s Story Progression with a MUCH better system. These mods are essential, and I could not play without them. I typically play each game in cycles, so this list will be updated when I’m in a Sims 3 cycle. I update this page as I add mods to my game or remove the ones I no longer use. Just like my Sims 2 mods list and S ims 4 mods list, this list is a constant work in progress. These are all the mods I use in my game, organized by category. Here is my recommended mods list for The Sims 3. Little Mortimer scours the web for all the best Sims 3 Mods.
